Abstract
Aspects of the disclosure provide an integrated circuit. The integrated circuit includes a first operational circuit module receiving a first supply voltage from a first voltage regulator that is external to the integrated circuit, and a first adaptive voltage scaling module to adjust the first supply voltage based on performance characteristics of the first operational circuit module. In an embodiment of the disclosure, the first adaptive voltage scaling module includes a first performance monitoring module. The performance monitoring module is disposed on the integrated circuit, and is configured to generate at least a first indicator corresponding to at least one performance characteristic of the first operational circuit module. Further, the first adaptive scaling module includes a first voltage requirement determination and voltage feedback generator module that is disposed on the integrated circuit, and is coupled to the first performance monitoring module. The first voltage requirement determination and voltage feedback generator module is configured to output a first feedback voltage signal having a voltage level that varies as a function of at least the first indicator. The first voltage regulator is configured to regulate the first supply voltage as a function of the first feedback voltage signal.
